SCPH-5502 8MB Modification

A while back I performed the 8MB modification to my 5502 PSX, and these are the photos.
If you want to modify your PSX for 8MB (only useful for development purposes) then see here.

A thanks goes out to Trimesh :praise

It's only useful for homebrew applications. No retail game will use it, nor will it speed things up.

Hello, good job! I saw the post of Trimesh, but I have many problems finding those DRAM memories. Where did you find it? It's so difficult. I have a DDR memory for PC that have 4 of those chips but are slightly different.. they are +5V, code: KM48C2104A.

I'm going crazy finding those chips.

Greets!
